Description

Technical Field

[0001] This utility model relates to the field of rotary kiln equipment, specifically to a rotary kiln slag removal device. Background Technology

[0002] A rotary kiln is a thermal equipment used for calcining, roasting, or drying granular and powdery materials. During the rotary kiln production process, slag falls into the slag flushing chute through the slag discharge port and is then water-quenched before entering the slag flushing pool. Due to the diversity and uncertainty of the slag type in rotary kilns, a slag flushing bar screen is installed at the slag discharge port to prevent slag from directly entering the slag flushing chute and causing blockage. The main function of this bar screen is to prevent large lumps from directly entering the slag flushing chute and causing blockage.

[0003] During the rotary kiln production process, the presence of the slag-flushing screen causes slag to accumulate on it during normal slag discharge, requiring periodic cleaning. Slag accumulation in rotary kilns has always been a major challenge in actual production. Currently, most rotary kiln slag cleaning methods rely on manual labor, resulting in low efficiency and poor performance. Therefore, we propose a rotary kiln slag cleaning device. Summary of the Invention

[0004] To address the problem of low slag cleaning efficiency and poor performance when manually cleaning slag in rotary kilns, this invention proposes a rotary kiln slag cleaning device. This device replaces the traditional manual slag cleaning method, is simple and convenient to operate, and enables rapid slag cleaning, reducing the labor intensity of operators.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A rotary kiln slag removal device includes a rotary kiln body and a kiln head hood disposed at one end of the rotary kiln body. A slag flushing chute is provided at the lower part of the kiln head hood, and a slag discharge pipe is provided between the slag flushing chute and the kiln head hood. The top end of the slag discharge pipe is closed and the bottom end is open. Several slag discharge ports are arranged in a circular array on the closed end of the slag discharge pipe. An adjustment component is provided inside the slag discharge pipe. Manhole channels are provided on both sides of the kiln head hood, and a slag removal mechanism is installed at one of the manhole channels.

[0007] Furthermore, the slag-clearing mechanism includes a cylinder, the telescopic rod of which passes through the manhole channel and is connected to a slag-clearing disc.

[0008] Furthermore, the adjustment component includes a turntable rotatably disposed inside the slag discharge pipe. The turntable has several fan-shaped notches arranged in a circular array. The slag discharge port is fan-shaped and penetrates the closed end of the slag discharge pipe. The notches and slag discharge ports are arranged in a one-to-one correspondence. A rotating shaft is disposed at the center of the turntable and is rotatably disposed at the center of the closed end of the slag discharge pipe.

[0009] Furthermore, a push rod is provided on the turntable, and a second cylinder is provided on the outer wall of the slag discharge pipe. An elongated hole is opened on the slag discharge pipe. The push rod passes through the elongated hole and is hinged to the telescopic rod of the second cylinder. The cylinder body of the second cylinder is hinged to the slag discharge pipe.

[0010] Furthermore, a bracket is provided on one side of the kiln head hood, the bracket is fixed to the ground, and the cylinder body of the first cylinder is fixed to the bracket.

[0011] Furthermore, the open end of the slag discharge pipe is connected to the slag flushing chute.

[0012] The beneficial effects of this utility model through the above technical solution are as follows:

[0013] This utility model provides a rotary kiln slag cleaning device. By incorporating a slag-pumping mechanism, a cylinder in the mechanism reciprocates, driving a slag-pumping disc to remove slag from the closed end of the slag discharge pipe. The slag then falls into the pipe through the discharge opening, enabling rapid slag removal and reducing operator workload. The circular array of discharge openings allows for multi-channel slag diversion, preventing single-point blockage. Furthermore, an adjustable component allows for adjustable overlap between the fan-shaped notch on the rotary table and the discharge opening, dynamically adapting to changes in slag type. This utility model eliminates the need to shut down the furnace during slag removal, enabling continuous operation. In particular, it replaces traditional manual slag removal methods, offering simple and convenient operation for rapid slag removal and significantly reducing operator workload.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1-6 As shown, this embodiment provides a rotary kiln slag cleaning device, including a rotary kiln body 1 and a kiln head hood 2 disposed at one end of the rotary kiln body 1. A slag flushing chute 3 is provided at the lower part of the kiln head hood 2. A slag discharge pipe 4 is provided between the slag flushing chute 3 and the kiln head hood 2. The top end of the slag discharge pipe 4 is a closed end and the bottom end is an open end. Several slag discharge ports 5 are arranged in a circular array on the closed end of the slag discharge pipe 4. An adjustment component is provided inside the slag discharge pipe 4. Manhole channels 6 are provided on both sides of the kiln head hood 2. A slag removal mechanism is installed at one of the manhole channels 6.

[0024] In this embodiment, the slag-clearing mechanism includes a cylinder 7, the telescopic rod of which passes through the manhole channel 6 and is connected to a slag-clearing disc 8. The length and width of the slag-clearing disc 8 are both greater than the inner diameter of the slag discharge pipe 4, providing full coverage for slag removal and eliminating blind spots.

[0025] This utility model provides a rotary kiln slag cleaning device. By setting a slag-pumping mechanism, the cylinder 7 in the slag-pumping mechanism reciprocates to drive the slag-pumping disc 8 to poke off the slag on the closed end of the slag discharge pipe 4. The slag then falls into the slag discharge pipe 4 through the slag discharge port 5, thus quickly cleaning the slag and reducing the labor intensity of the operator. The slag discharge ports 5 are distributed in a ring array to achieve multi-channel diversion of slag and avoid single-point blockage. Furthermore, by setting an adjustment component, the overlap between the fan-shaped notch 10 of the turntable 9 and the slag discharge port 5 is adjustable, dynamically adapting to changes in slag shape.

[0026] Please refer to this again. Figures 2-4 The adjustment assembly includes a turntable 9 rotatably disposed within the slag discharge pipe 4. The turntable 9 has several fan-shaped notches 10 arranged in a circular array. The slag discharge port 5 is fan-shaped and penetrates the closed end of the slag discharge pipe 4. Each notch 10 corresponds to a slag discharge port 5. A rotating shaft 11 passes through the center of the turntable 9 and is rotatably positioned at the center of the closed end of the slag discharge pipe 4. The overlap between the fan-shaped notches 10 and the slag discharge ports 5 is adjustable, dynamically adapting to changes in slag type. Specifically, for high-viscosity slag, a larger opening can prevent clogging; for low-viscosity slag, a smaller opening can reduce speed and prevent splashing.

[0027] Specifically, a push rod 12 is provided on the turntable 9, and a second cylinder 13 is provided on the outer wall of the slag discharge pipe 4. An elongated hole 14 is opened on the slag discharge pipe 4. The push rod 12 passes through the elongated hole 14 and is hinged to the telescopic rod of the second cylinder 13. The cylinder body of the second cylinder 13 is hinged to the slag discharge pipe 4. The extension and retraction of the second cylinder 13 drives the push rod 12 to rotate, and the push rod 12 pushes the turntable 9 to rotate around the rotating shaft 11, so that the overlap between the fan-shaped notch 10 of the turntable 9 and the slag discharge port 5 is adjustable.

[0028] In this invention, a bracket 15 is provided on one side of the kiln head hood 2, and the bracket 15 is fixed to the ground. The cylinder body of the cylinder 7 is fixed to the bracket 15. The bracket 15 is fixed to the ground by anchor bolts, and then the cylinder 7 is fixed to the bracket 15.

[0029] In this invention, the open end of the slag discharge pipe 4 is connected to the slag flushing chute 3. The slag falls into the slag flushing chute 3 through the slag discharge port 5, and then enters the slag flushing pool after water quenching.

[0030] It should be noted that a manhole door is provided on the manhole channel 6. After the slag removal is completed, the hydraulic cylinder 7 drives the slag-scraping disc 8 to retract from the kiln head cover 2, and the manhole channel 6 is closed again through the manhole door. In this utility model, the kiln head cover 2 adopts a double manhole channel 6 design, with a slag-scraping mechanism installed on one side and a maintenance passage reserved on the other side.

[0031] It is worth mentioning that the rotary kiln slag cleaning device provided by this utility model also includes a time relay and a solenoid valve. The output end of the time relay is connected to the control end of the solenoid valve to control the on / off state of the solenoid valve. The input end of the solenoid valve is connected to an external air supply source, and its output end is connected to cylinder 7. When the time relay is turned on, it energizes the solenoid valve, which then opens to control cylinder 7. Through the combined use of the time relay and the solenoid valve, the purpose of cyclically controlling the operation of cylinder 7 is achieved.

[0032] The working principle of this utility model is as follows:

[0033] When slag removal is required, the cylinder 7 in the slag-pumping mechanism reciprocates, driving the slag-pumping disc 8 to poke off the slag on the closed end of the slag discharge pipe 4. The slag then falls into the slag discharge pipe 4 through the slag discharge opening 5, enabling rapid slag removal and reducing the operator's workload. The ring-shaped array of slag discharge openings 5 ​​enables multi-channel slag diversion, avoiding single-point blockage. Furthermore, by setting an adjustment component, the overlap between the fan-shaped notch 10 of the turntable 9 and the slag discharge opening 5 is adjustable, dynamically adapting to changes in slag type. Specifically, the extension and retraction of the cylinder 13 drives the push rod 12 to rotate, which in turn pushes the turntable 9 to rotate around the rotating shaft 11, thereby making the overlap between the fan-shaped notch 10 of the turntable 9 and the slag discharge opening 5 adjustable.

[0034] In summary, this utility model eliminates the need to shut down the furnace during slag removal, thus enabling continuous operation. In particular, it replaces the traditional manual slag removal method, making operation simple and convenient, and allowing for rapid slag removal while reducing the labor intensity of operators.
